The Sol System

The Sol System is a star system in the OrionCygnus arm of the Milky Way galaxy. Its primary sun is Sol, a class G star.

Features
The Sol System is a 14-planet system. This is one of the highest number of planets in a system in the local star cluster. Another mind-boggling fact is that on four of these planets (Venus through Jupiter, that is.), native life developed.

The Sol system has moons and dwarf planets as well, some of them even supporting life. These non-planets that have life include:
 * Mars's moons, Phobos and Deimos
 * Dwarf planet Pluto
 * Europa
 * Titan
 * even The Asteroid Belt

History
Along with having its own colorful array of native lifeforms, the Sol system has been visited by many extrasolar aliens since it was forged in the heart of a hydrogen cloud. The Firstborn have been interfering with the Sol system since it formed, continuisly monitering the formation of life there, and striving to keep planets such as Venus and Mars habitable through their spectacularly advanced technology.
